removed dependency on sparse hash

needs more testing
Merge branch 'master' into remove-sparse-hash

Conflicts:
	Makefile
unsed svn dirs
compiles under clang all the way through (no multithreading)
this appears to be working - need to test on linux with gcc
code is now c++0x compliant

so I can now compile without -stdlib=libc++ which I think means means we can compile without setting the mac target to 10.9 which I think means we're good to go with the same compilation that anaconda is using!

of course, I'm not sure I nailed everything here, so if things start breaking, this is a good place to look.

would be nice to have unit tests to make sure.  but things are getting a LOT cleaner.  unit tests will come.
I think maybe possibly allowing build with only python setup.py install
set OPENMP to True in setup.py to try installing with openmp

off by default
a whole new day for accessibility

to tired to write down all the changes at this point.  It's half broken but this is a first shot at getting networks to work as Pandas would want them to.
add the current sample notebook and .gitignore too
reorg
more reorg
adding some basic tests and changing the api to use series objects
